International® ProStar™ Incorporates Design Features that Meet Needs of Women Drivers

Warrenville, Illinois - March 20, 2007
A new association, Women in Trucking, has formed to help interest more women in pursuing a career in trucking and also to help the industry become more "female friendly." International Truck and Engine Corporation is an inaugural corporate sponsor of the organization and Dr. H. Lenora Hardee, International Truck's manager of Human Factors and Ergonomics, is the group's treasurer and one of 12 directors.

"Traditionally, trucking has been male dominated, with men comprising more than 9-of-10 truckers, but we also realize that a huge group of male drivers will be retiring in the near future and we need to recruit more women to replace some of them," says Dr. Hardee, who helps designs International truck cabs to be more ergonomically correct for women. "Women in Trucking can help promote the industry to women."

As the only original equipment manufacturer among the organization's corporate sponsors, International Truck is taking an active role in promoting Women in Trucking. It is the primary sponsor of a Women in Trucking reception on Friday, March 23, at the Mid-America Trucking Show in Louisville, and the association's directors will be in attendance. As a corporate sponsor, International Truck also has invited 31 employees to be members of the organization from all parts of the organization.

"The Women In Trucking Association's mission is to attract more women into the trucking industry, and International's quest to provide the best cab environment for women shows that their focus complements ours," said Ellen Voie, chairwoman, board of directors, Women In Trucking, Inc., and manager of recruiting and retention programs at Schneider National, Inc. "We are proud to count International Truck as one of our corporate members, and sponsor at the Mid America Trucking Show."

As part of her ergonomics research, Dr. Hardee has measured more than 2,000 drivers, including drivers of heavy trucks, and is helping incorporate the findings of those measurements in the development of new truck designs. For instance, the new International® ProStar™, the company's flagship aerodynamic class 8 tractor, incorporates several design features that assist women and other drivers, including a closer dash board and lower shelving in the bunk.

Dr. Hardee and International Truck will be measuring drivers at the Mid-America Trucking Show at International Truck's booth. As an incentive, International Truck will give the first 100 women with a commercial drivers license who get measured a free membership in Women in Trucking, a $25 value, and $5 in cash.

"We need the data to continue to improve our tractor design for women and smaller drivers, and we also can help grow membership in Women in Trucking," says Dr. Hardee.
